Introduction To System
Size and Configuration
The iDCS 100 system consists of the basic Key Service Unit, an Expansion cabinet, Interface cards and
Digital keysets. The Key Service Unit begins with eight (8) keyset ports expandable to 18 analogue
C.O. line ports, or 24 lines if 4 BRI cards are used, or 32 stations. In addition, up to 8 keyset daughter
boards may be added to the system along with the optional 2 SLI card.
The Expansion cabinet A type has three Universal slots and one DCS slot for TEPRI(PRI) or VM
service, which provides the maximum configuration of 66 ports with analogue trunk lines or 96 ports
with Digital trunk lines.
The Expansion cabinet B type has two Universal slots and two DCS slot for TEPRI(PRI) or VM service,
which provides the maximum configuration of 58 ports with analogue trunk lines or 88 ports with
Digital trunk lines.
Two types of telephones can be connected to the system: proprietary digital stations called "keysets"
that connect to DLI (Digital Line Interface) ports and standard telephone sets, generally called "single
line telephones", that connect to SLI (Single Line Interface) ports.
The system also has an optional MISC card which provides Music on Hold facilities, two serial I/O
ports and other useful facilities.
The following charts (Figures 1–1, 1–2, 1-3, 1-4) describe configurations using the basic Key Service
Unit (KSU), an Expansion cabinet and expansion cards. However, by using the DCS's unique keyset
daughter boards (KDbs), which are installed in the base of a digital keyset, the capacity of the system
can be increased by one station per KDb. Installing a KDb–DLI adds another digital port while a KDb–
SLI adds a single line port. Mix and match these two types of KDb to get up to a total of 8 KDbs in the
system. Using this method allows the iDCS 100 to expand to a maximum of 64 stations. Adding the
optional 2 SLI card to the KSU provides a further two SLI ports. The combination of the basic 008 KSU
plus three expansion cards in the KSU plus three expansion cards and one DCS card in the Expansion
cabinet plus 8 KDbs plus a 2 SLI card provides a maximum configuration of 96 ports plus
Miscellaneous card.
1. Only one 2 SLI card can be installed in the system.
2. Only one MISC card can be installed in the system.
3. Only three expansion cards can be installed in the Key Service Unit.
4. Expansion A type consists of three universal expansion slots and one DCS card slot
for TEPRI(PRI) or SVMi-8.
Expansion B type consists of two universal expansion slots and two DCS card slot for
TEPRI(PRI) and SVMi-8.
5. Only 8 KDbs can be installed in the keysets connected to the 008 Basic KSU
6.
iDCS
100 system can have up to 48 stations if SVMi-8 is not used up to 40 stations if
SVMi-8 is used.
